EGG-TESTING MACHINE.

Specification of Letters Patent.

Application filed December 13, 1911. Serial No. 665,503.

To all whom it may concern:

Be it known that I, S UIRE J. Flsn, a citizen of the United States, residing at Jackson, in the county of Jackson and State have invented a new and useful Egg-Testing Machine, of which the fol- This invention relates to improvements in egg testing machines, the primary object of the invention being the provision of a machine containing a normally open electric lighting circuit, in which the illuminator is so disposed as to have interposed between it and a sight aperture or confiner, an egg carrier with a plurality of holders adapted each to contain an egg, the said egg to be disposed between the illuminator. and the sight aperture, said carrier being provided.

with a circuit closing means, whereby the circuit is energized successively or intermittently to cause the rays of light from each illuminator to be projected to give the desired transparency to the egg in what is known as candling eggs, or testing the same to sort out the fresh from the bad ones.

A further object of the invention is the provision of .an egg testing machine having a frame carrying a normally opened illuminating circuit, in combination with an end-' less carrier provided with a plurality of egg holders and with a circuit closing means, whereby as the eggs are disposed' into test ing or candling position, the circuit is successively or intermittently energized and the eggsilluminated one at a time so as to pro-. duce the desired transparency in 'assorting the eggs.

A still further object of the present invention is the provision-of a daylight can testing device, which may be readily used without the necessity of using the same in a dark room, the same being provided with an electrical means, whereby the trays carrying the eggs will close or energize the circuit during the testing or candling of the eggs.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it. being on erstood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a side elevation of the complete egg testing machine; Fig. 2 is a top plan view thereof. Fig. 3 1s, a longitudinal sectional view through the battery box and light confining tunnel of the machine, which in itself will constitute a small machine, while the machine, as shown in Figs. 1 and 2, is designed for testlng and I candling eggs in larger quantities. Fig. 4 is a perspective view of a plu rality of the egg holders and the adjacent portions of the carrier, portions of the carrier being broken away to show the circuit closers carried thereby. Fig. 5 is a diagram-' matic view of the lighting circuit.

Referring to the drawings, the numeral 1 designates the supports, which carry the battery box or main casing 2 of the machine. In the form shown in Figs. 1 and'2 journal brackets 3 and 3 are connected to and projected from opposite ends thereof and carry the respective wheels-4 and 4'.

Mounted sofas to pass above the upper surface of the box 2 and below the sameand around the respective wheels 4 and 4' is an endless conveyer 5 which has connected thereto alternating bridging conductors 6' and blocks ,6 of insulation, the bridging conductors being so disposed as to rest upon the respective contact points 7 and 8 of the electrical circuit, when the egg is directly above the lamp 10, as shown in 5, so as to close the circuit through the batteries ,9 and the lamp 10 .to produce the desired illumination for testing or candling the eggs, one at a time. This lamp 10, as clearly shown in Fig. 3 is removably mounted in the support. 11 disposed in the compartment 12 formed preferably'by a tube within the chamber or casing 2, the same being carried by the top thereof so that the lamp 10 will be disposed directly below the aperture 13 in the top of the casing or chamber 2. By this means the rays of light from the lamp will be projected through said aperture 13.

lonnected to thetop of the chamber or asing 2 upon each side thereof and ex ending equi-distantly from the, center of the aperture 13' is a light confining chamber or tunnel 1i provided with the sight tube or sleeve 15 which is'disposed to be in vertical alinement with the aperture 13 and lamp 10. By this means the rays of light from the lamp 10 will be observable directly through the tube or sleeve 1:"). when the circuit is closed or bridged by the circuit close g are made more readily discernible so t at a very rapid handling of the egg is perdisposed slots 17, whereby the egg may be' readily placed within t-heholder or removed therefrom. Disposed in the bottom of the respective holders 16 is a cup shaped ring 18 provided with an aperture 19 which is in alinement "with the aperture 20 of the carrier belt 5 By this construction it will be seen that when the holder. 16 is in the position shown inF-ig. 3 the conductor wire 6 will have bridged the points 7 and 8 closing the illuminating circuit so that the energized lamp 10 will have the rays thereof, projected through the apertures 13 and 20, to the egg within the holder 16 and that the party testing the eggs by sighting through the tube or sleeve will see ata glance the condition of the egg, such condition being readily observable, due to the transparency of the egg.

By this construction the defects within the mitted, and with a device as shown in Figs. 1 and .2 the eggs may be placedwithin the holder at the left thereof and by the ma 'such' tests.

nipulation of the crank or handle 21 may be moved in the direction of the arrow where they may be either removed'at the extreme right end manually, or fed by gravity to.

crates. p

Where a device is used employing simply the battery box and portions illustrated in Fig. 3, the carrier port-ion 5 is 'a single strip of material carrying in the neighbb-rhood of half a dozen of the holders 16 so'that the candling of eggs may be' done on a smaller' scale, yet in a thoroughlysatisfactory manner.

With this form of apparatus eggs may be candled or tested in daylight, as the peculiar arrangementof the illuminator 10, tunnel 14: and the egg carrier and circuit maker, provide a confining means for the rays of light so that the exterior light rays will have no-detrimental efiects in making By positioning the slots 17 so as to'open toward the closed portion of the tunnel that is toward the side walls thereof, jtheraysjof'light coming through the open ends offthe tunnel will be'excluded from the holders 16 so as not to in any way detrimentally efiect the-operation ofthe machine.

What is claimed (is; 1. An egg testing machine, having 1 an and a slidable circuit closer one to each egg holder carried by the holders.

An egg testingv machine, having an open electrical lighting circuit, a slidable egg carrier having an egg holder with a sight aperture to aline with the light of the lightinigcircuit, and a circuit closer carried by the carrier to successively open and closethe circuit for each egg holder to energize the light. 7

3. An egg testing machine, havinga normally open electrical circuit including an illuminat-or, and a movable egg tray and circuit closer disposed to successively open and close the circuit as the egg tray disposes an egg above the illuminator.
